I'm running SP2 and see no real stability change. I had problems with my office2k updates making word, outlook, etc. crash after opening. I've had problems with the march compatability update, but that is my CD-ROM won't work after applying it. I also have a problem with the Agent newsreader causing BSOD's when running other programs at the same time. I've learned what caused each and have corrected the problem or know what to do so it doesn't occur. No stability problems with anything else. As far as the BSOD's, Agent isn't written for NT or 2K so there is that problem. I'm looking for a good newsreader that can combine messages for the different parts and do it easily.
